Day Two of Al Davis Football, Inc. versus fired former Raiders coach Lane Kiffin saw the two combatants face-to-face Tuesday for the first time since September 2008. This expensive legal skirmish over disputed back pay is getting nastier by the day, and neither side seems eager to blink.

In Kiffin's battle to recoup about $2.6 million in salary withheld when Davis fired him for cause Sept. 30, the new University of Tennessee head coach showed up at an Oakland hotel to stare down his former boss as part of his arbitration hearing.

Kiffin was deposed for more than seven hours Monday at a San Francisco law office. Davis' deposition was scheduled for 11 a.m. Tuesday in Oakland - he arrived 20 minutes late - and the Raiders' owner appeared surprised but unflappable when he encountered Kiffin outside the hotel lobby. He waved to two Chronicle NFL writers who met him in the hallway outside the deposition room.
